Abstract: For manufacturing ophthalmic lenses and other optical form bodies made of plastic material, plastic form parts are used which are made by non-cutting shaping and are then further worked by mechanical production steps. Said plastic form parts are circular blanks (1) made of two different plastic materials which are firmly joined to each other. Thereby, an interior lens element (2) that consists of a high-quality material is concentrically surrounded by a ring fixture (3) which consists of a low priced material.  Either surface of the lens element (2) may feature any given geometry. During mechanical working, the ring fixture (3) is used for mounting as well as for depositing and, in addition, for stabilizing the workpiece (9). For this reason it is partially maintained throughout the mechanical working and is cut off at the end only.

Title: Dual motor strapper
Inventor: NIX ROBERT J
IPC: B65B13/18
Filed: 2003-06-13
Granted: 2009-08-11
Abstract: A pneumatic strapping tool for tensioning a strap around a load, adhering the strap onto itself, and cutting a feed end of the strap includes a piston, a weld motor operably connected to the piston and a vibrating weld element operably connected to the piston for contacting the strap and adhering the strap onto itself. A tensioning motor is configured for unidirectional rotation. A feed wheel is operably connected to the tensioning motor by a drive assembly to tension the strap prior to adhering the strap onto itself. A transmission cooperates with the drive assembly and is switchable between a first state in which the transmission engages the drive assembly to permit only one-way rotation of the drive assembly and a second state in which the transmission permits two-way rotation of the drive assembly. The strapping tool includes a self-contained pneumatic module that is removably mounted to a cylinder housing. The module includes a compressed gas inlet, a plurality of valves and passageways between the inlet and the valves to provide compressed gas to the cylinder housing, a pneumatic weld motor and the pneumatic tensioning motor. The module includes at least one timer for operation of the weld motor and for providing pressure to the cylinder. An articulating guide is disposed at the strap path and moves between an open path position when the tensioning motor housing is pivoted to the loading/unloading position and a closed path position when the tensioning motor housing is pivoted to the strap engaging position. The guide aligns the strap with a second strap to which the strap it is adhered and aligns the straps with the feed wheel and anvil.

Patent CA-2570345-C (CA)
Inventor: SUTIVONG ARAK
IPC: H04L1/20
Filed: 2005-06-07
Granted: 2012-01-03
Abstract: Techniques for adjusting transmit power to mitigate both intra-sector interference to a serving base station and inter-sector interference to neighbor base stations are described. The amount of inter-sector interference that a terminal may cause may be roughly estimated based on the total interference observed by each neighbor base station, channel gains for the serving and neighbor base stations, and the current transmit power level. The transmit power may be decreased if high interference is observed by a neighbor base station and increased otherwise. The transmit power may be adjusted by a larger amount and/or more frequently if the terminal is located closer to the neighbor base station observing high interference and/or if the current transmit power level is higher, and vice versa. The intra-sector interference is maintained within an acceptable level by limiting a received SNR for the terminal to be within a range of allowable SNRs.
